I suggest the best way to learn the system, well at least what I did was to go throuhg the system 2-3 times. I Pred about 5-10 books fully, I mean all of the steps. The other thing I found really usefull was photoreading the PRWMS 5-10 times a day for a week or two. If you try to listen to the course while sleeping I think there will be minimal benefit compared to acually doing it. Since you have the course PR the PRWMS and the NB books 5 times a day for like three weeks. I did this for a while and I had a lot of spontaneous activation when using the system and reading the forum

Good Luck.
